DTSD5-反篡改多阶段米

The use of innovative metering technology provides cost-effective metering that is highly secure and maintains a high degree of accuracy over its full operating range. DTSD5-A poly phase meter is suitable for CT or direct connected, residential, commercial and even light industrial polyphase applications. Cost Effective Revenue Metering The energy meter is designed to provide cost-effective functionality themeter combines proven metering technology with a reliable electro-mechanical register. The metering system is 2-element for 3 phase 3 wires system and 3-element for 3 phase 4 wire system. Meter is programmed on the measurement mode at the factory prior to dispatch: The total energy measurement from the three phases can be optioned in vector consumption or absolute value consumption. Records import and export energy flow in separate registers, and add the values in both directions as the labeled energy consumption. Reliability Digital measurement technology with proven long-term capability, use of long life components and special care in the manufacturing process guarantee consistent accuracy and reliability over the meter's life time. Meter case Made of self-extinguishing polycarbonate and can be recycled at the end of the meter life. It assures double insulation and up to IP53 protection level against dust and water penetration. Local metering data display (LCD) Automatic Scroll mode Manual scroll (by button) Programmable data set and sequence LCD back-light: optional LCD display when power absent: optional Communication Port Equipped with an optical port and Rs485 (optional) for meter reading.
